1. An unintelligent or moronic person, derogatorily likened to a mentally disabled person (i.e., one who may drool involuntarily). The Internet is filled with drool buckets like you who make ignorant claims with no basis in reality.

2. A figurative bucket needed to collect saliva as a result of seeing someone or something particularly attractive. I'm going to show you my grandfather's vintage 1967 Corvette—get your drool bucket ready!

3. Someone, especially a baby, who drools a great deal. He's such a happy baby, but my goodness, he's a little drool bucket!
